An electronic calculator carries out input of data, such as numeric values, stores data therein, and performs operations and processing of the input data according to the operation of necessary function keys. Further, inputted matrix data is stored in relation to one code so that when operating the matrix data, the code is utilized for inputting an operational expression, whereby the procedure for inputting such data for operation can be considerably simplified. If it is desired to preserve input data, the data can be protected by preventing rewriting or redefinition thereof. Also, data processing is enabled which excludes any data abnormally different from other data, thereby enhancing the reliability of the results of the data processing.
